You may be right, but it's odd for that to happen on a weekend and to push the fees up as well. Often we see congestion but low fees, as nobody wants to pay more than they have too. Only time that fees get pushed up like this (excluding temp fads like ordinals introduction) is when BTC is in full boom mode and that isn't happening yet IMO because if it was I would be hearing about it everywhere in the meatspace, which I'm not.
